android - 如果在编辑文本上单击两次，Drawable 会更改

Question

我有两个编辑文本视图，在其上添加了两个可绘制对象。一个是edit_text_bottom_line，另一个是edit_drawable。

现在我想显示编辑文本输入的edit_text_bottom_line可绘制onClick。所以我可以看到这样的布局：

这行得通。现在，当我们再次单击编辑文本输入并出现浮动提示时，我想再次显示另一个可绘制对象，此时它应该如下所示：

这也有效。但是现在，如果我再次单击编辑文本视图，那么它会更改布局 edit_text_bottom_line 可绘制对象，如下所示：

我想在用户开始输入时显示蓝色可绘制对象，直到他在该编辑文本视图上以及在编辑文本获得焦点之后。

如何确定编辑文本是否聚焦？我从 onFocusChangeListener 尝试，如果编辑文本集中显示蓝色可绘制但它在下次单击时消失。

布局：

            if(b) {
                edt_Item_Name.setBackgroundDrawable(ContextCompat.getDrawable(SearchActivity.this, R.drawable.edit_text_bottom_line));
                edt_Item_Unit.setBackgroundDrawable(ContextCompat.getDrawable(SearchActivity.this, R.drawable.edit_text_bottom_line));
                edt_Item_quantity.setBackgroundDrawable(ContextCompat.getDrawable(SearchActivity.this, R.drawable.edit_drawable));
            }
            else {

            }
        }
    });

或者更确切地说，应用两种布局，我在主题中将强调色设置为蓝色，因此默认情况下，如果聚焦，编辑文本采用蓝色，这很好，但是当我更改灰色线的可绘制对象时，我如何才能转到默认的蓝色线编辑文本？

请帮忙，谢谢。。

只需做一件事，使您的输入文本布局如下：

 <android.support.design.widget.TextInputLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintTextAppearance="@android:style/TextAppearance.Small">

                    <EditText

                        android:layout_width="match_parent"

用这个改变你的 xml TextInputLayout 和 TextInputEditText：

<android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_item_quantity"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="20dp"
            android:layout_marginRight="20dp"
            android:layout_marginTop="02dp"
            android:textColorHint="@color/grey">

            <android.support.design.widget.TextInputEditText
                android:id="@+id/editTextItemQuantity"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:layout_gravity="center_horizontal"
                android:layout_marginBottom="05dp"
                android:layout_marginLeft="10dp"
                android:layout_marginRight="10dp"
                android:hint="@string/quantity"
                android:imeOptions="actionDone"
                android:inputType="number"
                android:textColor="@color/lighttextcolor"
                android:textSize="14sp"
                android:textStyle="bold"
                android:theme="@style/style_edittext_color_control"/>
        </android.support.design.widget.TextInputLayout>

在你res/values/styles.xml添加这个：

<style name="style_edittext_color_control" parent="Theme.AppCompat.Light">
        <item name="colorControlNormal">@color/grey</item>
        <item name="colorControlActivated">@color/blue</item>
    </style>

希望这会给你正确的结果。
